[Beowulf] CephFS

[Tom Harvill]

Hello,

Question: is anyone on this list using CephFS in 'production'?  If so, 
what are you using
it for (ie. scratch/tmp, archive, homedirs)?  In our setup we use NFS 
shared ZFS for /home,
Lustre for /work (performance-oriented shared fs), and job-specific tmp 
on the worker nodes
local disk.

What I really want to know is if anyone is using CephFS (without 
headache?) in a production
HPC cluster in place of where one might use Lustre?

Thanks!
Tom
